“…Therefore, it is difficult to design a optimized satellite platform structure with optimized performance relying on traditional method and experience. Fortunately, numerical models could be established with utilization of CAD/CAE techniques to substitute real structures for FEA [1][2][3] (Finite Element Analysis), parameters used for this numerical design and calculation can be selected with flexibility, also, they can be used repeatedly during analysis and optimization process. Recently, it is an obvious trend to develop CAD/CAE integrated system for the creation and computation of FEA models, some research has brought forward brand-new approaches, such as the Design Compiler 43® [4] developed in Stuttgart University, IDEA [5] in NASA, etc.…”

A structured frame for the design optimization problem of satellite platform structure was established through the definition, flow and modification research of design parameters in the ANSYS/CATIA system. Problems with creating complex satellite structure FEA (Finite Element Analysis) models were discussed, including the idealization of real structure, as well as embedment of APDL (ANSYS Parametric Design Language) programme developed specially for the pre-processing and post-processing of FEA model. The optimization model was established under structural design requirements, and a graded optimization method was applied for calculation. Light-weight design schemes for two satellite platform structure were obtained through the subsequently optimization implemented using approaches put forward previously. The optimization design problems of two satellite platform structure were settled well, and work done in this paper provides certain reference value for optimization of other spacecraft structures.
